鼻咽部淋巴瘤的影像诊断及鉴别诊断

摘要

Objective: To investigate radiological findings and differential diagnosis of nasopharyngeal lymphoma. Method: CT or MRI findings in 18 patients with lymphoma of nasopharynx proved by pathlogy were retrospectively analyzed. Result: The lesion included one or two side masses of nasopharynx in 12 cases,mucosa thickening in 6 cases, tonsil swell in 12 cases. The density of masses was mild or moderate enhancement in 12 patients. Lymphoma invaded nasal cavity、opopharynx、 base of tongue or tonsil, usually masses can be differented from longus capitis. Conclusion: Relatively characters were finded in nasopharyngeal lymphoma . CT or MRI can demonstrate the extent and depth of lesions, and nasopharyngeal lymphoma can be differented from nasopharyngeal carcinoma and nasopharyngitis.%目的:探讨鼻咽部淋巴瘤的影像特征及鉴别诊断.方法:回顾性分析我院经病理证实累及鼻咽部的18例恶性淋巴瘤的影像资料.结果:病变表现为单侧或双侧肿块12例,软组织增厚6例,淋巴结肿大13例,12例鼻咽部肿块轻中度强化.病变可浸润鼻腔、口咽、舌根及扁桃体,与头长肌可分界.结论:鼻咽部恶性淋巴瘤的影像表现有一定特征,CT及MRI能够显示病变的范围和浸润的程度,并与鼻咽部炎症及鼻咽癌鉴别.
